GEORGE ELMER HEATON, OF THREE RIVERS, MICHIGAN.

BICYCLE.

SPECIFICATION forming part of Letters Patent No. 558,069, dated April14, 1896. Application filed September 3, 1995. Serial ,N' 561,276. (Nomodel.)

To all whom it may concern:

Be it known that I, GEORGE ELMER HEATON, a citizen of the United States,residing at the village of Three Rivers, in the county of St. Joseph andState of Michigan, have invented a certain new and useful Bicycle, ofwhich the following is a specification.

My invention relates to improvements in bicycles, and more particularlyto an attachment to the ordinary single bicycle.

The object of my invention is to provide a means which will adapt anordinary single bicycle for use as a tandem bicycle capable of easilycarrying two persons, and other minor objects which will appear in thedetailed description. I accomplish this object of my invention by thedevice and mechanism shown in the accompanying drawings, in which-Figure 1 is a view of an ordinary diamondframe bicycle with myattachment in place. Fig. 2 is a detail view of the framework of myattachment detached from the machine. Fig. 3 is an enlarged detail viewof the clamp and horizontal arms, showing the method of attaching myimproved device to the lower portion of the bicycle-frame. Fig. 4 is anenlarged detail sectional view on line 4 4 of Fig. 3, looking in thedirection of the little arrows at the ends of the section-line. Fig. 5is an enlarged detail sectional view on line 5 5 of Fig. 2, lookingdown.

Similar letters of reference refer to similar parts throughout theseveral views.

Referring to the drawings and the lettered parts, it will be seen thatto the frame of an ordinary bicycle is joined my new attachment, inFig. 1. A is the head of the main frame. B is the lower forward brace ofthe frame and B is the diagonal brace of the frame, which unite at thelowerpart and form a bearing for the main crank-shaft of the machine.

My improved device consists of an additional head 0, which bears anordinary bicycle-fork O. Extending downwardly and rearwardly from thishead C are braces D, which have outwardly-projecting studs J at theirlower part to engage into the lower end of the fork A of the rearmachine. The braces D extend on rearwardly and pass to each side of themain frame of the bicycle, where they are clamped in position by theclamps I,

which are secured in place by the bolts N N, suitable protecting-blocksM M being placed between the braces. Extending downwardly from the topof the head 0 is the brace D, which is joined by suitable brazing to thebraces D and is curved upwardly and rear wardly, so that its rear end issubstantially parallel to the head of the main frame. A supplemental.head E extends downwardly parallel with the head A of the main frame andis secured thereto by clamps F F, which are ordinarily two-member hingedclamps. I11 the supplemental head E is inserted a handle-bar post G,bearing handles K at the top. A short arm G projects out from the lowerend of the handle-bar post G and is connected by a link H to anoutwardly-projecting arm 0 on-the fork O of my attachment for thepurpose of uniting the two handle-bars to the steering-head so that theyshall act together.

A seat is secured in the main head A of the machine for the support ofthe forward rider. The handle-bars K, being attached to the post G underthis forward seat, project outwardly and upwardly to each side of theseat. A suitable crank-hanger I is secured to the braces D a little tothe rear of the lower end of the fork A, and in this hanger is inserteda crank-shaft I, and on the shaft is supported a sprocket-wheel I, whichcarries a suitable sprocket-chain which passes back over an additionalsprocket-wheel 0f the same size on the crank-shaft of the main machine,this additional sprocket-wheel not being detailed out in the drawings,as it can be placed upon the shaft in a variety of positions.

" It will thus be seen that a tandem machine ing a seat on the head ofthe machine, and

the handle-bars in the supplemental head adapted to project out at eachside.

I desire to state that my attachment for bi cycles can be considerablyvaried in its details without departing from my invention. It would bepossible to dispense with the braces D and substitute therefor thebraces D, (indicated by dotted lines,) and secured in substantially thehorizontal position to the forward head 0 and supplemental head E. Thisis the construction adapted for use where the attachment is designed tomake a tandem. wheel adapted for the use of men. As I have shown thedevice in full lines the forward position is designed and intended forthe use of female riders.

My attachment can be considerably varied in its details withoutdeparting from my invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The combination with the frame of an ordinary bicycle, of anadditional head, 0; a fork, O, in said head, 0; braces, D, extendingdownwardly from said head, 0, and adapted to attach to the lower end ofthe fork of the main bicycle-frame by means of studs, J, and extendin grearwardly and secured to the lower part of the frame of the bicycle byclamps, L; the supplemental head, E, with clamps, F, thereon to besecured to the head of the main frame of the bicycle; a handle-bar postinserted into said supplemental head; an arm, G, on said post, and anarm, C, on the fork, O; a link, H, for connecting the said armstogether; the curved brace, D, extending from the additional head, 0,downwardly, rearwardly and upwardly to the supplemental head, E; a seatto be secured to the forward head of the main bicycle-frame; handle-barssecured in the supplemental head, E, proj ecting outwardly and upwardlyto each side of the forward seat; suitable handle-bars supported on theforward head, 0; the crankhanger, I; the crank-shaft, l, therein; asprocket-wheel of the same size on the crankshaft of the main machine,all coacting together substantially as described for the purposespecified.

2. The combination with the frame of an ordinary bicycle, of anattachment consisting of an additional head, 0; the Supplemental head,E, located parallel to the head of the main frame; suitableconnecting-braces from the head, E, to the head, 0; downwardly andrearwardly extending braces, D, from the head, 0, engaging the lower endof the fork, A, of the main frame and clamped to the lower angle of themain frame of the bicycle; and suitable clamps clamping the supplementalhead, E, to the main head, A, of the main frame, substantially asdescribed.

3. An attachment for a bicycle consisting of an additional head, C,suitable brace-rods extending therefrom to connect it to the head of themain frame of the bicycle to the lower end of the fork of the mainbicycle and to the lower angle of the frame, as specified.

' In witness whereof I have hereunto set my hand and seal in thepresence of two witnessse.
